Automotive hose is a special component designed to respond to high temperatures, advances in fuel system technology, and the combined pressures of fuel formulations that rapidly degrade inappropriate and inferior hose materials. Diesel, biodiesel and various alternatives to ethanol and methanol-based gasoline all have different chemical compositions. They have individual performance characteristics that make some fuels more corrosive than others. The development of electronic fuel injection technology has increased the working pressure and enhanced the destructive effect on fuel line pipe materials.

1. How do you choose fuel line pipes and replace them?

Obviously, all fuel line pipes are different. Each fuel line pipe is designed to operate in a specific environment and conform to OE specifications. Installers encounter a series of fuel line pipe installation problems, and installing an inappropriate hose may change the design of the vehicle's fuel system. If the engine fails, the repairman may have to undertake expensive repairs.

Ten common causes of fuel line pipes assembly failure include: poor hose selection, fluid incompatibility, insufficient insertion depth, twisted hose, hose over wear/undercooling temperature, hose minimum bending radius over hose, kinking or extrusion, incorrect tightening of clamps, and expiry of service life.

For each replacement job, there is a matching fuel line pipe within gates' range, providing reliable and safe service. Multi-purpose hose with small gate diameter, working pressure up to 1mpa, suitable for all fuel systems except biodiesel. Fuel line pipe is a small diameter hose with a durable and oil resistant textile shell, available in 7 different sizes, up to 0.6mpa working pressure. Special fuel line pipes with very small diameters are suitable for connection and vacuum hoses are also available. There are also five sizes available for flexible hoses to connect the fuel port and fuel tank of the vehicle.

2. What are the features of plastic fuel line pipes?

Plastic fuel line pipes are lightweight, cost effective and allow for complex geometry, which makes them very attractive to manufacturers. Plastic fuel line pipes enable manufacturers to optimize cost, space, weight, and installation parameters while exceeding safety and emission requirements. The plastic fuel line pipe contains an EVAL barrier layer that provides exceptional permeability resistance and thus complies with stringent international emission regulations and durability characteristics.


3. What is the most common source of leaks in the fuel line pipe?

Carburetors are the most common source of leaks, so start checking. The fault could be water coming into the carburetor, not a leak. Check the connections between the fuel line pipe and carburetor, then check the other connections, all the way to the tank. Place the car on a ramp or axle frame and inspect the underside of the floor. Bend the hose between your fingers to show cracks or cracks. Press the clamp and the metal joint to see if they are loose. Touch the joints to see if they are wet. Gasoline may flow along the fuel line pipe before it starts to drip, which can be misleading. Once you find a leak, you can make a temporary repair, but anything damaged should be replaced completely as soon as possible. If one of the plastic lines is damaged, the entire line must be replaced, as the temporary lap joints do not remain sealed for long. Some blends of petrol sold in Europe are likely to cause plastic fuel pipelines to expand or swell. Sinking fuel line pipes are the first sign. Be sure to clamp the pipe firmly.


Fuel line pipes need proper usage as well as repairment. If you have any questions with your fuel line pipes, feel free to consult us.
